【 摘 要 】

[Introduction] In order to obtain the safe and economic operation plan of microgrid, a mathematical model of optimal economic operation of microgrid based on support vector machine regression theory was proposed. The load forecast of distributed power sources in microgrid was realized, and the distribution was analyzed according to real-time electricity price. The output of the power supply, and the corresponding theoretical basis. [Method] In order to construct the microgrid model as accurately as possible, aiming at the operating cost, environmental protection cost and comprehensive benefits of the system, a mathematical model of optimal economic operation based on common five distributed power sources was constructed, using Yalmip/CPLEX. The model was solved and the real-time output of each distributed power source was obtained. [Result] The calculation results show that the scheduling scheme with the comprehensive benefit can achieve the lowest operating cost of the microgrid, and coordinate the economic and environmental protection of the microgrid. [Conclusion] The model can lay a theoretical foundation for the research on the optimal utilization of microgrid grid-connected resources and the improvement of power supply reliability.
